N2 - BACKGROUND: Anemia is linked to impaired outcome in patients with cardiovascular diseases. We sought to characterize the impact of baseline anemia on mid-term outcome after transcatheter aortic valve implantation (TAVI).METHODS AND RESULTS: Data of 1201 consecutive TAVI patients were retrospectively analyzed. Baseline anemia was defined according to the WHO (hemoglobin <12g/dl [female], <13g/dl [male]). It was prevalent in 59.0% of patients and associated with a higher preoperative risk (STS-PROM 7.8 ± 5.7 vs. 6.2 ± 4.1%, P < 0.001). Survival was similar at 30 days (90.5 vs. 91.2%, P = 0.626) but NYHA functional capacity was impaired in patients with baseline anemia (classes III/IV: 20.6 vs. 15.6%, P = 0.006). Low baseline hemoglobin (OR 0.85, CI 0.73-0.98, P = 0.025), blood transfusion (OR 2.42, CI 1.38-4.28, P = 0.002), and bleeding complications (OR 2.21, CI 1.27-3.81, P = 0.005) were in addition associated with acute kidney injury after TAVI. Three-year survival was reduced (49.6 vs. 64.9%, P = 0.002) and baseline anemia was linked to increased mid-term mortality (HR 1.43, CI 1.13-1.82, P = 0.003), however its effect was surpassed by the adverse impact of periprocedural complications.CONCLUSIONS: Baseline anemia was associated with increased morbidity and mortality after TAVI. Preprocedural hemoglobin levels need to be assessed for risk stratification and blood conservation management seems essential. As a potentially modifiable target, the role of pretreatment of anemia prior to TAVI remains to be determined.
